Results and discussion
Self-heating substances / mixtures
- Key result
- Test procedure:
- 100 mm sample cube at 140°C
- Result:
- negative outcome (no effect observed)
Any other information on results incl. tables
No spontaneous ignition occurred and only a slight exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required.
After the experiment, the test item had turned into a red/brown (molten) residue and was partially collected in a container that was placed below the cube. It indicated that the test item had molten and decomposed and/or reacted during the experiment.
Applicant's summary and conclusion
- Interpretation of results:
- other: not classified based on GHS or CLP criteria
- Conclusions:
- The substance is not a self-heating substance.
- Executive summary:
In a GLP study according to UN Test N.4, a negative result was obtained using a 10x10x10 cm sample cube at 140°C. From this it was concluded that the substance is not a self-heating substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
